Anomalies in high-bitrate video on CDR

[heavyharmonies]

UPDATE: I've tried 3 different brands of CDR media, as well as trying CDRW, just in case the DVD player wsn't liking the media I initially was using. No dice... Any help on this?

************************************************** *******
Doing some playing around tonight with various encoding schemes for testing, and I've run into the following problem (it may be that DVDR as opposed to CDR will fix this since they read differently, but I'm not sure):

(same AVI source in all cases)

352x240 MPEG1 CQ100 Max bitrate 4000 kbps. - plays fine in my DVD player.
352x240 MPEG2 CQ100 Max bitrate 7000 kbps 48khz audio (basically 1/4 D1 spec) - plays fine in my DVD player
352x480 MPEG2 CQ100 Max bitrate 7000 kbps 48khz audio (1/2 D1 spec) - audio/video stutters every few seconds
720x480 MPEG2 CQ100 Max bitrate 7000 kbps 48khz audio (full D1) - audio/video stutters every few seconds

Is there an incompatibility with using Nx480 resolutions on CDR media? I thought NTSC SVCD standard was 480x480 (which I haven't tried).
Or is the problem that I'm using a DVD template in TMPGENC and there's something in there that's choking my DVD player since the media is CDR not actually DVDR (but if that's the case, why does the 1/4 D1 video play fine)?

Too much data for the DVD player to keep up with on a CDR?

Thanks,

Your problem was a little bit different from mine, but I'll shoot. I was doing a fair amount of encoding in a 352X480 mode as well (Kwag's template.) In my player (Panasonic RV-31), I would get video and audio stutters all the time if the audio was encoded in 48k. I could encode it 352x240, 48k and it would work fine, but 352x480, 48k wouldn't. I just drop the sample rate to 44.1k whenever I do 352x480, and it works like a charm for me.

Not sure if it will work for you or not, but it's worth a try.

Hmm, odd. I'll try re-encoding with the exact same specs, but 44.1 khz audio.

Since 44.1 isn't part of the DVD spec, I'm hoping this is a problem that will go away on DVDR as opposed to CDR... and had UPS not [CENSORED] up and rerouted my incoming DVD burner to Seattle instead of central Illinois, I'd be able to verify this... *grumble*

What I don't get though, is if your premise is accurate, why the 352x240 48Khz mpeg doesn't exhibit this behavior....
